SAML 2.0 & 1.1 Assertion Parser & Validator

=============

saml20-maintained is a fork of a fork of saml20. It is the same library with updated versions of vulnerable dependencies, additonal fixes and support for more providers as needed. The new package is published here - https://www.npmjs.com/package/@boxyhq/saml20

$ npm install @boxyhq/saml20

rawAssertion is the SAML Assertion in string format.

Parses the rawAssertion without validating signature, expiration and audience. It allows you to get information from the token like the Issuer name in order to obtain the right public key to validate the token in a multi-providers scenario.

var saml = require('@boxyhq/saml20');

saml.parse(rawAssertion, function(err, profile) {
	// err

	var claims = profile.claims; // Array of user attributes;
	var issuer = profile.issuer; // String Issuer name.
});

rawAssertion is the SAML Assertion in string format.

options:

• thumbprint is the thumbprint of the trusted public key (uses the public key that comes in the assertion).
• publicKey is the trusted public key.
• audience (optional). If it is included audience validation will take place.
• bypassExpiration (optional). This flag indicates expiration validation bypass (useful for testing, not recommended in production environments);

You can use either thumbprint or publicKey but you should use at least one.

var saml = require('@boxyhq/saml20');

var options = {
	thumbprint: '1aeabdfa4473ecc7efc5947b18436c575574baf8',
	audience: 'http://myservice.com/'
}

saml.validate(rawAssertion, options, function(err, profile) {
	// err

	var claims = profile.claims; // Array of user attributes;
	var issuer = profile.issuer; // String Issuer name.
});

or using publicKey:

var saml = require('@boxyhq/saml20');

var options = {
	publicKey: 'MIICDzCCAXygAwIBAgIQVWXAvbbQyI5Bc...',
	audience: 'http://myservice.com/'
}

saml.validate(rawAssertion, options, function(err, profile) {
	// err

	var claims = profile.claims; // Array of user attributes;
	var issuer = profile.issuer; // String Issuer name.
});

In order to run the tests you must configure lib.index.js with these variables:

var issuerName = 'https://your-issuer.com';
var thumbprint = '1aeabdfa4473ecc7efc5947b19436c575574baf8';
var certificate = 'MIICDzCCAXygAwIBAgIQVWXAvbbQyI5BcFe0ssmeKTAJBgU...';
var audience = 'http://your-service.com/';

You also need to include a valid and an invalid SAML 2.0 token on test/assets/invalidToken.xml and test/assets/validToken.xml`
